Draining roller

ABSTRACT

The present invention relates to an improved structure of a spiral draining roller, characterized in that a plurality of interlaced diagonal partition blocks, and having a design of spiral stairway draining grooves. By the simultaneous rolling of both the front and rear rollers while squeezing the water absorbing foam, drainage is provided for the dirty water to flow outwards towards either side of the grooves. In doing so, it further increases the effect of draining the dirty water by the left and right wings simultaneously and completely.

BACKGROUND OF THE INVENTION

[0001] 1. FIELD OF THE INVENTION

[0002] The present invention relates to an improved structure of a spiral draining roller, characterized in that a plurality of interlaced diagonal partition blocks, and having a design of spiral stairway draining grooves. By the simultaneous rolling of both the front and rear rollers while squeezing the water absorbing foam, drainage is provided for the dirty water to flow outwards towards either side of the grooves. In doing so, it further increases the effect of draining the dirty water by the left and right wings simultaneously and completely.

[0003] 2. DESCRIPTION OF THE PRIOR ART

[0004] A mop is a necessary cleaning tool for all kinds of environments such as the household and office. As it is often said, if one wants to do a job right, one must have the right tools. Upon taking a look of the current market, one finds a glut of foam mops that come in all kinds models, yet what distinguishes the better from the worse is nothing more than the degree of humanistic design in its mechanics. However, when we take a closer look into the structural design of the water-draining property of these water-absorbing foam mops, we find that there were some early designs of single-rowed wheel with upper/lower small-surface-squeezing method of water drainage, but in avoiding the incapacitation of rolling-squeezing of such design at the tail-end section that results from over-squeezing beyond the foam head, its effectiveness of drainage was drastically reduced. Therefore, a double-wheeled squeezer was recently introduced, but it turns out that the structure is too heavy and inconvenient to use, which caused users to seriously dislike using these mops. In addition, both drainage designs use the front and rear rolling-squeezing method to remove the dirty water, which is totally without any transversal twisting to achieve the result of removing the debris, and so there is definitely a need for further improvements.

SUMMARY OF THE INVENTION

[0005] Therefore, the primary objective of the present invention is to provide an improved spiral draining roller structure, more particularly to a spiral draining roller structure having a plurality of interlaced, diagonally-partitioned stairway-like draining grooves on the protruded surface of the roller, such that the simultaneous rolling of both the front and rear rollers while squeezing the water absorbing foam drains the dirty water outwards towards either side of the grooves, and further increase the effect of draining the dirty water by the left and right wings simultaneously and completely.

[0006] The secondary objective of the present invention is to provide an improved spiral draining roller structure, more particularly to a spiral draining roller structure having a plurality of interlaced, diagonally partitioned, stairway-like draining grooves on the protruded surface of the roller such that the front and rear rollers can simultaneously squeeze the water absorbing foam to the farthest extent possible, where the foam then is allowed to return to its original position. In so doing, the maximum rolling distance as well as a 100% removal of water from the foam is achieved.

DELTAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0012] With reference to the drawings and in particular to FIGS. 1 through 5. The present invention is an improved spiral water draining roller structure comprising a holding rod 1; a U-shaped base 2 being disposed at the front end of the holding rod 1; a water absorbing foam 3 is disposed inside the base 2, and a foam base 31 being engaged into the top edge of the foam; a pulling rod 5, 5A, each being disposed on a side of the screwed foam base 31 and passing through the base and pivotally coupled to both sides of a pulling handle 6 on the holding rod 1, characterized in that:

[0013] a latching groove 71 being disposed on both end of a positioning axis 7 at an opening in front of the base for latching and positioning a C-shaped buckle 9 for the coupling of the roller 8, wherein a plurality of diagonal partition blocks 81 being designed on the surface of the roller, and comprising a spiral stairway draining groove 811.

[0014] Please refer to FIG. 4 for a preferred embodiment of the present invention. By means of the front and the rear roller to simultaneously squeeze the water absorbing foam for self rotation such the partition blocks on the surface twist the foam for dirt removal, and the water with dirt will be sequentially drained along both sides of the spiral stairway draining groove 881. When the foam is squeezed to the utmost end, the partition block will be attached and returned to its original position to maximize the rolling traveling distance and completely squeeze the water away in order to enhance the effect of squeezing the dirty water away simultaneously along both wings of the foam.

[0015] Therefore, in summation of the above description, the present invention meets the requirements of patentability, which is hereby submitted for patent application. While the invention has been described by way of example and in terms of a preferred embodiment, it is to be understood that the invention is not limited thereto. To the contrary, it is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims therefore should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures. 

I claim:
 1. An improved structure of a spiral draining roller, comprising a U-shaped base disposed at the front end of a hold rod of a mop, and a roller being pivotally coupled between the bases, and a second base further comprises a water absorbing foam, and a pulling rod being disposed on both sides at the top edge of the foam, and the pulling rod passes through the base and pivotally coupled to a pulling handle on the holding rod, characterized in that: a plurality of partition blocks are disposed on the protruded surface of said roller rod thereby forming a spiral draining groove, such that by means of squeezing the water absorbing form on the front and the rear end of the drainage roller, it provides a way of completely draining the dirty water through the water draining grooves towards both sides of the foam.
 2. The improved structure of a spiral draining roller, wherein said partition block on the surface of the roller is inclined with an angle or in the shape of letter “S” for squeezing the water absorbing foam of the roller to the utmost rear end and being attached to its original position on its return trip in order to fully squeeze the dirt away from the foam.
